Tetraethyl lead is a metal anti-knock agent that is extremely cost effective, powerful and unmatched byethanol gasoline, which undoubtedly has some harmful effects. However, it is the best product availabletoday to solve the problem of low grade gasoline and increase the octane number.

Tetraethyl lead was once widely used as an additivein gasoline to increase the octane rating of the fuelto prevent detonation within the engine, thusenabling the use of higher
compression ratios,thereby increasing the efficiency and power of thecar engine. This compound is commonly used as anadditive in automotive gasoline to increase theoctane number and as an anti-shock detonationagent, thereby extending the life of the components.
